Delivery times

We aim to deliver in-stock mainland orders in 1–3 working days, allowing up to five working days, subject to availability and delivery access. We will contact you to arrange delivery. Any different lead time will be confirmed before ordering.

Pre-orders are delivered after the stated warehouse arrival date, which is an estimate and may change. A preferred delivery day is a request for our team to confirm, not a guaranteed booking.

Sample delivery

All samples are sent free by Royal Mail Tracked 24, separately from full-size materials. Delivery is typically 24–48 hours after collection, rather than a guaranteed arrival time. Tracking details are emailed once collected.

Order before 3pm Monday–Thursday for that day’s sample collection. Orders placed later are prepared for the next available collection.

Eligible small fixings also receive free Royal Mail Tracked 24 delivery. For mixed baskets containing boards or larger materials, the applicable project delivery charge remains payable; samples and eligible fixings do not add an extra delivery charge.

Mixed orders and product lead times

We aim to deliver mixed orders together. Items may be packed separately, and a product with a longer stated lead time may affect your delivery date. Check each product page for availability.

Container or manufacturer-direct orders may have separate lead times and delivery fees. Please contact our team before ordering.

Access and unloading

Please tell us about narrow lanes, restricted access or other site constraints when ordering. This helps us plan your delivery.

Large or heavy orders may arrive on a pallet; pallet deliveries are usually kerbside. We will contact you if assistance is needed for unloading.

Collect from our Manchester warehouse

Collection is usually ready within 24 hours. You will receive an email after placing your order. Please wait for confirmation that your items are ready before travelling.

Composite Decking Subframe Post – 80mm x 80mm x 3m | Heavy-Duty, Low-Maintenance Support

Create a strong and long-lasting foundation for your composite decking with our Composite Subframe Post, engineered for stability, durability, and low maintenance. Measuring 80mm x 80mm x 3000mm, this robust support post is the perfect alternative to traditional timber, offering a rot-proof and weather-resistant solution for any decking project.

Unlike wooden subframes, which require regular treatments and are prone to decay, our composite posts are made from recycled plastic and wood fibre - ensuring maximum strength with zero ongoing maintenance. Whether you're building a domestic patio or a large-scale commercial deck, this structural post delivers the reliability and lifespan your project deserves.


Key Features:

  • Dimensions: 80mm (T) x 80mm (H) x 3000mm (L)

  • Application: Ideal for creating a long-lasting decking subframe or raised platform base

  • Material: Recycled composite blend – resistant to rot, warping, and insect damage

  • Low Maintenance: No need for sealing, painting, or treating – ever

  • Moisture & UV Resistant: Designed to perform in all UK weather conditions

  • Eco-Friendly: Made from sustainable materials – a smarter, greener choice over timber

  • Easy to Work With: Can be cut and installed using standard woodworking tools


Use this subframe post as the core structural element beneath your composite decking, delivering peace of mind for years to come. Its moisture-resistant, heavy-duty construction ensures your deck stays safe, level, and solid - without the hassle of timber maintenance.

Build it right the first time – with Majestic’s Composite Decking Subframe Post.
